SASH FASTENER.

Application flied 'November 15, 1921-. seriai No. 515,24zsfl To @ZZ lwwmy t may concern:

Be it known that I, JosnrH F. SCHwnR, a citizen of the United States, residing in Pittsburgh, in the county ofrillegheny and State of Pennsylvania, have invented a new andl useful Improvement in Sash Fasteners, Vof which thefol'lowing is a full, clear, and exact description. A

vrIhe present invention relates to sash fasteners of the type adapted to hold both the upper and lower sashes in any one of a plurality of adjusted positions, and to prevent rattling of the sashes.

It has heretofore been proposed to construct sash `fasteners comprising strips adapted to be secured to the upper and lower sashes, respectively, and provided with a series of projections so disposed that different projections were engagedV according to the position of the sashes. Cooperating with such strips, as shown, for example, in the patent to Balier, No. 539,565, of May 21, 1895, may be spring members each having a single projection adapted to engage di'erent ones of the. first mentioned series of projections.V Such constructions have, however, necessitated cutting away a con siderable portion of the window frame to permit movement of the spring members to inoperative position. This requires a special frame construction, as the usual window frames are comparatively thin, to provide housings for the sash weights. By the present invention, there is provided a construction which obviates this objection.

Also, I am aware that it is old to provide spring members with locking perforations, but such constructions Vhave not permitted a. plurality7 o-points of engagement aft one time between each of the sash members and the spring members., such as may be obtained by the present invention.

' vfurthe-r object of the present invention is to provide a construction, of the type rcerred to which is Vadtip-table tor use with windows having metallic weather stripssuch as i ordinarily used.

The foregoing and other objects of the present invention, 'together with their at*- te-ndantadvantages, will be appare-nt as the invention becomes. better understood by ret-V erence to the accompanying specific-ation and drawings forming aAv p-art thereof, it beingpremised that changes may be made in the detailsof construction and man-ner of operation without departing from the scope et' my invention.

Figure 3 is a transverse sectional view Yon theli'ne III-III of Figure 2';

Figure 6 is a perspective view of one oi the bearing plates;Y Figure 7 is ay'vertical sectional view through aportion of a 4window frame provided with a sash fastener constructed in accordance with the presentY invention, one of' the sa-shesbeing partly broken away L; and Figure 8 is a vertical,sectionalV view on the i-ine VIII-VIII of Figure 7, the sashes being removed.

Asshown in the accon-ipa-nying drawings, a standard window frame comprises, on each side facing strips Q and a: connecting strip 3 forming a housing ijto'r the sash weights. The strip 3 onV each side ofthe window may be provided with a groove 5 Jfor the reception ot Vthe usual' parting bead 6 and with guide strips 7. In each` of the spaces between the parting bead 6 and the'g'uide strip 7, may be mounted metallic weather strips S' of any standard construction. Thesash frames 9,'as illustrated in Figures )Zand 3 may be provided with grooves' 10 for the reception'ofl the weather stri-ps;` Y

In applying the present 'invention to a standard construction'ofthis nature,a por.- ti'en oit one end of each of the weatherstrips S is cut` away. The strip 3 adjacent; such cut away portions is v also-slightly recessed, as indicated at 1l.. for the reception of; resi-lient'locl'ing members l2 each having open ings at one *en-d for the reception ofj taistening means 13. for holdin-gl tlej same in posi-tion. From the point of' attachment of.Y the locking members to the frame, they are ibo bent slightly in such manner that` themarina-ll A tendency of the lock-ing members is tolie in a ifivsas the position illustrated in Figure 1. The shown in Figure '7, preventing any further intermediate portion oi each of the resilient looking members 12 may be provided with a series of rectangular openings 14;, and the tree ends of the locking members are bent inwardly to provide cam engaging portions 15. The resilientA locking members are mounted in position on the trame in such manner that theJ cani engaging portions 15 lie in a common transverse plane.

At substantially its intermediate portion, the parting bead on one side of the frame is cut away and the strip 3 is. recessed to receive a bearing plate 16. Adjacent one end, the bearing plate 1G is provided with an inwardly extending portion 17 having upper and lower openings 18 and 19 vformed therein. The bearing plate 1G is mounted in position in such manner as to overlie the cam engaging portions 15 of the resilient locking members, and carries an actuating member 2O having cams 21 formed therein in such manner as to engage the cani engaging portions 15 when the parts are in position. One end of the actuating member 2O is mounted in one or the other of the bearing openings 18 or 19, depending upon which side of the window trame has the locking device secured thereto, and the opposite end thereof projects outwardly beyond the facing strips 2 through a groove 22. At its extreme outer end it may be provided with squared portion 23 adapted to receive a detachable actuating knob or key 24 'for rotating the same. The strip 3 may be providedwith openings 25 immediately underlying the cam engaging portions 15 to permit movement thereof inwardly when the actuating member 20 is turned to move the resilient locking members to inoperative position, in which they extend substantially parallel to the weather strips 8.

For cooperation with the openings 14: in the resilient locking members 12, there is mounted on one edge of each of the sash frames an angular locking member 26 secured thereto in any desired manner, preferably with one portion extending under the sash rope 27. These members Iare in turn provided with a series of equally spaced projections 2S adapted to extend through the openings 11- when the locking members 12 are in operative position,

lith such a construction, when it is desired to adjust either or both of the sashes to an intermediate position :tor purposes oi ventilation, the knob 2i will' be applied to the actuating member 23 and it will be turned to move the locking members 12 to inoperative j'iosition as before described. At this time, the sashes may be adjusted vas desired. Thereafter, the locking members 12 will be released, whereby the openings 141- will engage a plurality ofthe projections 28 on the locking members 26, as cle-arly unautaorized movement ot the sashes.

Preferably at. least one olf each pair of locking members 12 has its extreme end bent outwardly to toi-m a sto 29 to prevent turning the actuating member 20 more than 90. )it this time, the pressure of the resilient locking members is exerted substantially in line with the cani portions 2-, whereby the resilient locking members are held in their inoperative position. By providing a bearing plate 16 with upper and lower bearings 18 and 19, as described, it will be apparent that the bearing plate may be reversed and the actuating member changed from one bearing to the other, Aaccordingl to which side of the window 'carries t the locking device. rl`his permits the position of all of the parts of the lock to be readily reversed, and adapts the construction to use under a large variety of conditions.

rlhe removable knob 24C is very desirable in case the fastener is used in sanitariums or the like in which it is undesirable to have the setting of the windows tampered with by any of the patients.

ln window constructions where the metallic weather strip is not utilized, there may be substituted for the locking members 2G, substantially U-shaped locking members 26 having a double row of projections 2S', and the resilient locking members 12 may likewise be provided with two rows of open-- ings 14. Such a construction insures even greater rigidity.

The advantages of the present invention arise trom the provision oi, a sash fastener adapted to provide a plurality of points of locking engagement between the frame and the sashes.

Further advantages arise from the provision ot the removable actuating knob, and 'troni the reversible bearing plate whereby the fastener may be used with a large variety of window trame. constructions.
